stream_cdda, stream_vcd: check read buffer size

Browse Source 
These assumed that the buffer provided with fill_buffer() was at least
sector sized, instead of checking the size parameter.

This is just a cleanup, since every caller made sure to align everything
on sector sizes, if a stream has the sector size set.
